Early days but seems to be working

My 15 year old has been using this for almost 3weeks now. She's found it easy to use, instructions were very clear and her skin does appear to be improving. Will definitely continue to use. Seems a bit over-engineered with the need to buy a new "activator" every 30days - clearly a business model that's only going to work if the results are really good. Do need to find 10minutes every day which is going to be a challenge in term time!
